Accessibility
The reading design aims to make the full text and its qualifications available without a special interaction. Claims, evidence limits, prices and source descriptions should remain readable together.
Adjust the reading size
The text control switches the publication’s body text between 22 and 26 pixels. Browser zoom and text preferences remain available. Long headings, source names and navigation links are intended to wrap rather than be cut off, including on narrow screens.
The setting is temporary and returns to the default after reloading. The control does not require an account or save a preference.
Navigate the visible document
Links and controls are intended for keyboard use with a visible focus indicator. Topic links lead to complete fixed reader records, and source references connect the text to its cited record. The article contents and library use ordinary links.
All four paragraphs in each reader record, the source references and related reading remain open. The article’s substantive sections are not placed behind an answer control or a source drawer. The essential reading and navigation remain available without JavaScript; the interactive text-size toggle requires it.
No certification claim
These are design commitments, not a certification of accessibility or a guarantee about every browser, assistive technology or external destination. The publication does not claim an independent accessibility audit or clinical review through this page.
External sources and seller pages have their own interfaces. If a limitation prevents access to information needed for a health or purchase decision, this site should not be treated as a substitute for appropriate professional help or the responsible seller’s actual records. No support-response service or emergency contact is offered here.
